2. Adding Substacks and Palettes
Instead of cluttering the main screen with controls, you can create a new substack/card with all the settings.
You can read more about this here: Modeless stacks and palettes
1. Click on "File", then "Create a substack for flappyBird"
2. Name it e.g. "Prefs", add to it - sliders, labels and a button to close it
3. Add scripts to the buttons:
A. On the Gravity slider, put the script:
on scrollbarDrag x
global gravity
put x into gravity
end scrollbarDrag
B. On the Speed slider, put the script:
on scrollbarDrag x
global colSpeed
put x into colSpeed
end scrollbarDrag
C. On the Close button, put the script:
on mouseUp
go to stack "FlappyBird"
close stack "Prefs"
end mouseUp
4. On the Stack "Flappy Bird", add a button "Settings"
put the following code on the button
Now when you press it, a small palette will pop up to change any settings
Instead of "modal" you can put "modeless", "palette" or "modal"
The different types of stacks that you can create are:
Modal - for blocking other actions
A modal dialog box is a window/stack that blocks all other actions as long as the stack is displayed. An example is "Ask" and "Answer" dialog boxes. You can not do anything else as long as it is open.
modal stack "Pop-up"
or
go stack "Pop-up" as modal
Modeless - for utilities and settings
A modeless dialog box is a window/stack that cannot be modified except for fields. It is used for find/replace and preferences. They can stay up while you play the game.
modeless stack "Find/Replace"
or
go stack "Find/Replace" as modeless
Palettes - for Tools
A palette always floats above all other window. They are most often used on cards that need to stay available like tools and they do not block other actions. In LiveCode, the Tools palette and the Property Inspector are palette style windows
palette stack "My Tools"
or
go stack "My Tools" as palette
Customizing them. You can change what controls are shown by setting the decorations:
set the decorations of stack "myStack" to ...
"close" -- show only the close gadget
"close,minimize" -- show the close and minimize gadgets
to empty -- completely hide the titlebar
to "default" -- reset the titlebar to the standard look for the window mode
